What are the things to be considered while buying a screen for an XBox 360 with Kinect?
- Backlight Module
- View Angle
- HD Ready or Full HD
No, the only thing that really matters is the space between you and the Kinect sensor (you'll typically want at least 2 or 3 meters if possible; not 100% sure about the actual specs).
Theoretically, you can play any Kinect game with your TV turned off.
The only games that are screen dependent are classic light gun games, because those used the displayed screen to determine whether you hit or not.
But for all modern games - no matter whether it's Kinect or Move - all that really matters is the distance between you and the camera, as that defines the space where you're able to move, where the system is able to see you, etc.
Of course, a too small or too big screen can be a problem for you personally (e.g. you're no longer able to read text at the recommended distance), but it will never interfere with the actual input/control system.
I believe an important point you are overlooking is Input Lag. The last thing you will want is a display that is the right size, with great color, good viewing angle, etc that has a delay between your button 'clicks' and their action on the screen. I have found this web site (Display Lag Database ) to be a big help when I was purchasing a new monitor for my PS3/Xbox360 setup after discovering the my New 42" LG TV is virtually unusable because of the Input Lag.
